> The general purpose DataStream job currently does not have any functionality to simulate user job failures.
> We can achieve this by:
> - Adding a simple-pass map function, that throws exceptions after a certain criteria is met
> - To allow for the end-to-end tests that we have in mind, criteria could be to fail after 1) processing X records, and 2) Y completed checkpoints (see FLINK-8977)
> - We should also allow specifying how many times to fail. Some chaos monkey tests (see FLINK-8973) would need to continuously fail several times, while FLINK-8977, for example, only needs to fail once.
